The Warning

The Warning (El aviso, 2018) is a Spanish thriller-fantasy you can watch online on iFILM, directed by Daniel Calparsoro. The premise is a locked-room puzzle stretched across a century: mathematician John, played by Raúl Arévalo, uncovers a pattern of killings at a single gas station going back to 1913 — always the same date, always a ten-year-old boy among the victims.

John calculates that the next event should fall on April 12. But his friend was shot on April 2, two days off — which means the cycle is intact and the next killing hasn't happened yet. Running alongside his investigation is young Nico, a ten-year-old who has received a threatening letter no one else believes. The film cuts between the two timelines, tightening the knot as the date approaches.

The Warning is built for viewers who like their genre fiction structural — more equation than jump scare, with a payoff that hinges on whether the maths actually holds. Stream The Warning (2018) online on iFILM.
